The 2026 development
MemoryArena tested whether agents use earlier experience to complete interdependent later tasks.
The governance gap
Memory that is useful can also be stale, contaminated or applied outside its original scope. Evaluation has to test refusal and scope, not only recall.
Where CAIN-42 fits: Moat 2 — Security-Context Continuity
Core question: Does authority survive every boundary? Identity, scope and delegation are carried across tools, agents, memories and systems.
Score memory on four axes: recall, scope, freshness and authority effect. A memory that is recalled into the wrong tenant or purpose is a failure, not a hit.
How the wiring works
- Define the memory's tenant, purpose and validity window.
- Test recall on the intended task.
- Test refusal on an out-of-scope task.
- Test supersession when the source changes.
What is real today
LIBRARY Production code and tests exist in this repository; there is no hosted route for this exact use.
The memory firewall and continuity tests exist. No MemoryArena implementation is present.
